No one can deny that blockchain is a kind of technology that is at a premium. Its potential is used in a great number of industries. The food industry, which has recently developed transparency in food supply chains, is one of them.
Blockchain frenzy in supermarkets
The applications of blockchain in the food industry have been mentioned about many times before and, undoubtedly, it can be said that it brings various benefits. One of the benefits is, for instance, the increased consumer confidence in the producer which, in turn, affects sales.
The recorded increase in demand for products in Carrefour after placing them on the blockchain is an ideal example here. A French retailer made an attempt to use this technology to track the supply of food products such as dairy, meat and fruits. And it turned out to be an amazingly good decision.
It is commonly known, that by purchasing food for themselves, people would prefer to be aware of where it comes from. If blockchain can guarantee that the information it contains cannot be removed or changed then, they will trust it more than they trust ordinary labels.
There are hundrets of people saying that what we eat is not that essential. Let's note how the fashion for healthy eating has grown recently, however. There are not only information websites, applications or groups devoted to this topic. Together with the increase of awareness, the requirements increase as well.
Blockchain - what could go wrong?
Even though the arguments presented above are sufficient to understand what we can gain from blockchain and why implementations of this technology are crucial not only for consumers, but also for retailers, there are negatives too. And they cannot be missed. It does not, of course, directly hit the blockchain itself.
Let's then think about what might go wrong while using this technology to track the history of the product. As the Techwire Asia claims, one of the leaders of agribusiness, Craig Heraghty, told the Australian media recently that blockchain is clearly astounding in theory, but there is no guarantee that everything will go as planned with it.
"The weakest link in the chain is not blockchain or any technology, the weakest link is the piece of sticky tape that puts the label on the package."
Heraghty believes, that the illusion of identity provided by systems based on this technology is a quite disturbing trend. How to resolve it? The retailers will have to make every effort to prevent it, after all.
The case is mainly about the fact that nothing stands in the way for dishonest shop owners to start manipulating labels and QR codes. That, on the other hand, would also be a shot in the knee for supermarkets lika that.
Retailers such as Carrefour and Walmart will doubtlessly strive to find a solution to get rid of this problem. By focusing on technology, these stores already regularly gain a noticeable advantage in the market.
